Possible erratum with the statement that "50% more power is provided for unconfigured or suspended devices (150mA up from 100mA)."
The USB 3.0 spec says that "Suspended devices, whether configured or not, shall limit their bus power consumption as to the suspend mode power requirements in the USB 2.0 specification".
Table 7.7 of the USB 2.0 specification states that low-power devices are limited to 0.5mA and high-power devices are limited to 2.5mA during suspend.
